Day 14- A Non-Fictional Book

Okay, someone help me out- what is the last non-fictional book you have read? I don't remember my last one except for the book I just got from Drew's Book fair- Rocks & Minerals (Scholastic True Or False) * I have learned a great deal about Rocks and Minerals, but as far as a Non-fiction book for me? Not so much.

Are you reading any non-fictional books that are good? Let me know in the comments!
